Industrial robot and cable guiding device for this robot and use of the device

Abstract

An industrial robot with an upper robot arm ( 1 ) that comprises a first arm part 2 ) arranged to rotate at a second arm part ( 3 ), whereby a cable set ( 4 ) extends through both arm parts whereby a guiding device ( 6 ) for the cable set is arranged at the upper robot arm where the guiding device comprises cavities ( 21, 22 ) running through it arranged to guide at least one line within it in a sideway direction and to allow the displacement of at least one line within it in a longitudinal direction. The present invention also relates to a guiding device for a cable set for an industrial robot with a rotatable robot arm and to a use of the guiding device for an industrial robot with a rotatable robot arm.

What is claimed is:  
     
       1. Industrial robot with an upper robot arm that comprises a first arm part arranged to rotate around a second arm part, whereby a cable set extends through both arm parts, wherein a guiding device for the cable set is arranged at the upper robot arm, the guiding device comprising through cavities arranged to guide at least one line of said cable set within it in a sideways direction and to allow the displacement of at least one line within it in a longitudinal direction, the guiding device further comprising a plate for guiding the cable set with ring-shaped cavities and a holder for the plate for guiding the cable set, wherein the holder is provided with inwardly projecting lips adapted to accommodate a respective ring-shaped cavity of the plate for guiding the cable set. 
     
     
       2. Industrial robot according to  claim 1 , wherein the cavities are arranged to keep at least one line separately in them. 
     
     
       3. Industrial robot according to  claim 1 , wherein the guiding device has a disk-like shape. 
     
     
       4. Industrial robot according to  claim 1 , wherein the guiding device is arranged to be separated, whereby the plate for guiding the cable set is dismounted arranged in holder. 
     
     
       5. Industrial robot according to  claim 1 , wherein the guiding device for a cable set is arranged at the end of the upper robot arm. 
     
     
       6. Industrial robot according to  claim 1 , wherein each of the ring-shaped cavities is arranged at least around the periphery of the plate for guiding the cable set. 
     
     
       7. Guiding device for a cable set for an industrial robot with an upper robot arm, wherein the guiding device for the cable set comprises a plate for guiding the cable set with through cavities and a holder for the plate for guiding the cable set, said through cavities arranged to allow the displacement of at least one line of said cable set within it in a longitudinal direction, wherein the holder is provided with inwardly projecting lips adapted to accommodate a respective ring-shaped cavity of the plate for guiding the cable set. 
     
     
       8. Guiding device according to  claim 7 , wherein the plate for guiding the cable set and the holder have a disk-shaped design. 
     
     
       9. Guiding device according to  claim 7 , wherein the plate for guiding the cable set can be opened.
